Phentermine and topiramate extended-release [package insert]. Mountain View, CA: Vivus; 2012.
Phentermine/Topiramate
• Very potent weight loss agent• Positive studies in Binge Eating (topiramate)
• Significant number of potential Adverse Events (two drugs two sets of potential AEs)• REMS program: potential for teratogenicity, cleft lip
and cleft palate• Suicide, mood, and sleep disorders (topiramate)
• Acute myopia and glaucoma (topiramate)• Cognitive impairment (topiramate)
• Phentermine: sympathomimetic that can increase heart rate and blood pressure
Phentermine and topiramate extended-release [package insert]. Mountain View, CA: Vivus; 2012.
Clinical Pearls and Phentermine/Topiramate ER
• Balance significant weight loss with potential for adverse events
• In the pivotal trials they did allow pts on SSRIs to be in the study
• Despite the fact that this medication contains a sympathomimetic it did not typically increase blood pressure but does increase pulse
• Recommend the middle 7.5/46mgs dose • Weight loss at 2 years very similar to highest dose• If the patient needs to stop they do not have to
taper down

Adverse Events
• Nausea • (Forced Titration in studies)
• Constipation• Headache• Vomiting• Dizziness• Insomnia
• Take second dose late afternoon not late evening
• Dry mouth
Naltrexone ER /Bupropion SR 32mg/360 mg
N=2545%
Clinical Pearls Bupropion/Naltrexone
• May have added benefit in the depressed obese patient • Be cautious with combining with other depression
meds (potential for interaction)• Has potential to work on “Cravings” and food reward
type eating• Recommend slow titration due to nausea • May not need to go to the highest dose, in clinical
practice many patients lose weight on lower doses
Drug-Drug and other interactions
• Ticlopidine and Clopidogrel (Plavix) • Decrease dose to 1 BID
• Seizure risk with bupropion thus do not give to patients with a seizure history
• Bulimics • One to two mmHg rise in blood pressure and pulse (check
BP the first 12 weeks) • Do not give to patient on chronic opioids• Do not give with high fat meal

Randomize to placebo or study drug and followed for 3-5 years
This has to be completed for most weight loss medications as well as diabetic medications

Liraglutide 3.0 mg FDA allowed use of Liraglutide 1.8 mg dataLiraglutide felt to be CVOT safe and a CVOT not required
“Orexigen shared the CVOT data with over 100 individuals both within and outside the company (data leaked)When the FDA found out the company was told to continue the trial but must do a second CVOT trial. The CVOT interim data was released by the company to the public in a patent application and the executive committee of the study felt the study was unblinded And it was completely terminated.

Cardiovascular Safety of Lorcaserin in Obesity
Randomize 12,000 patients with Cardiovascular disease (75%) and/or Diabetes (57%) with multiple cardiovascular risk factors
Randomized half the patients to lorcaserin and half to placebo
Primary outcome: cardiovascular event • (example stroke, myocardial infarction, heart failure, angina etc.)

Adverse Events in Pivotal trial
• Nausea - 40.2%• Titrate slowly
• Vomiting - 16.3%• Pancreatitis - 0.2%
• Placebo - 0.0• Diarrhea – 20.9%• Constipation – 20.0%• Decreased appetite - 10.8%• Hypoglycemia in Diabetic Study
• Increased in patients on sulphonylureas
Clinical Pearls Liraglutide
•Useful in the obese pre-diabetic and diabetic patient
•Non-stimulating (non-sympathomimetic) and useful in the cardiovascular patient•Improvement in blood pressure •Improvement in lipids
•Titrate slowly as GI side effects are common•Has data showing weight loss in the patient that has already lost weight on their own
Bottom Line
For the high risk cardiovascular patient• Lorcaserin = safe• Liraglutide = safe (superiority)
At this time no completed CVOT studies • Naltrexone/Bupropion not recommended• Phentermine/topiramate not recommended

Patient with DM2
struggling with eating
large portions of food feeling out of control
• 42 year old female newly diagnosed type 2 diabetes • Sent by her primary care provider • The patient states she has always been healthy and
is very upset by the diagnosis of “diabetes” and asked to see a specialist
• Her only problem in life has been her weight. As early as a teenager she started gaining weight and has struggled her entire adulthood
• She is a very successful vice president of a biomedical research start up and has a MD/PhD in neurology
• She is very well dressed, engaging, and obviously highly intelligent
History
• She typically starts work at 8 AM and finishes around 8 PM. She realizes the need to be honest, and tells you about her struggles with food when she gets home from work.
• She will buy a “small pizza” on the way home from work. The pizza is 4 large slices and she has the intention of eating one or two slices.
• When she gets home she ends up eating the whole pizza and feels like she just can’t stop herself. She feels “very guilty” after she finishes as “I know better”. She only does this alone, and at times eats until she is uncomfortably full.
• This struggle with food will happen 3 to 4 times a week
Definition of Binge eating • Eating a large amount of food (Ex. two times a normal
portion) in a discrete period of time • Feeling out of control when eating
• Eating alone usually due to embarrassment • Eating rapidly• Eating until uncomfortably full• Continuing to eat even if not hungry • Feeling guilty, depressed or unhappy after binge eating • No compensatory behavior (Ex. vomiting, abuse of laxative, etc.)
Binge eating in the DM2 population• Prevalence varies from approximately 10 % to 25 % in women with DM2
• (compared to 2% in the general population)• Patients presenting to a weight loss clinic have a higher prevalence of 28%
• 47% of these pts will have impaired glucose tolerance (DM2 or Pre-DM2) • In the “Look Ahead trial” that studied weight loss in obese DM2 patients,
Baseline Binge eating in the last 6 months prior to starting the study 11.2% • DSM 5 criteria 1.1%
• Swedish study that followed Binge Eating disorders patients over 17 years found that one third became type 2 diabetics that required DM medications

Binge eating disorder and Diabetes type 2
• Binge eating disorder is very common in the patient with DM2• Patients with Binge eating disorders and diabetes will be have
higher BMI compared to other diabetics• Binge patients may present with diabetes at a younger age
• (Scripps Clinic in house data)
• Binge appears to be an independent risk factor for DM2 • Binge eating disorder has an ICD 10 code

NeuroBiology of Binge Eating in Humans
• Genetic Form: MC4 receptor defect • Binge eating is a major phenotype of gene mutations of the
hypothalamic Melanocortin 4 Receptor • This receptor controls satiety or fullness after a meal • Heterozygous patients will present with severe obesity, hyperphagia, and
severe insulin resistance
• 5.1% of patients with severe obesity have a mutation of the MC4R receptor
• Treatment options: medications that can work post MC4R or downstream from MC4R Ex: GLP-1 working thru the hindbrain
• Branson R, Potoczna N, Kral J, et. Al. Binge Eating as a Major Phenotype of Melanocortin 4 Receptor Gene Mutations NEJM 2003; 348:1096-103
NeuroBiology of Binge Eating in Humans• Reward Circuitry involved in Binge eating
• Mesolimbic and Mesocortical Pathways (Reward Pathways) • Mesolimbic dopamine release seen in reward eating
• Lower dopamine activity in obese patients leads to overeating • Nucleus Accumbens – GABAergic and Glutamatergic activation produces
eating behavior • Potential areas to Treat Binge eating disorder
• Medications that can increase dopamine• Bupropion and Stimulants
• Medications that work thru the GABA system• Topiramate and Zonisamide = decreased food intake

Back to our patient: Physical exam and lab values:
• BMI of 41 Blood pressure 148/78 pulse 82 • A1c of 7.2 on Metformin 1,500 mgs per day • Urine mildly positive for microalbumin • Feet neurovascularly intact
• Type 2 diabetes with proteinuria • Borderline Blood pressure • Binge Eating Disorder (BED)
Treatment options in Binge Eating Disorder
• Approved Binge Eating Disorder treatments• Lisdexamfetamine dimesylate (L-lysine conjugated to
dextroamphetamine)• Not approved for weight loss or obesity treatment• Can Increase in blood pressure and pulse
• Increase associated with longer length of treatment • Common side effect leading to discontinuation (9%)
• Insomnia, Anxiety, Irritability, increased blood pressure, etc.
• Lisdexamfetamine should be avoided in patients with Heart disease
